1. Open http://jsbin.com/vocix/1/quiet with devtools closed 2. Refresh the page, note that onupgradeneeded is called each time 3. Open devtools 4. Refresh 5. onupgradeneeded no longer called, as if the error didn't happen I guess something is preventing the error propagating? Chrome has a very similar issue https://code.google.com/p/chromium/issues/detail?id=395472
